EKYTHEMA PAKATEIMMA. 121 



ERYTHEMA PARATEIMMA. 



This form of erytheniatous inflammation is due to pres- 

 sure, and no more favourable instances can be adduced of it 

 than the galls due to the saddle or collar. 



Saddle-galls or saddle-scalds are frequently seen on ladies' 

 horses, on the off-side of the withers. They are due to the 

 saddle not fitting. The shoulder-galls, due to the collar not 

 fitting, are especially met with in summer weather, and more 

 in young horses first put to work than in seasoned horses. 



The first symptom is that of the animal evincing pain on 

 pressure being applied to the skin where it has been bruised. 

 A swelling then occurs, and chronic induration of the skin may 

 result, or perhaps more frequently an abscess forms. If the 

 case is attended to early, and proper treatment applied, both 

 the formation of the pus and the thickening may be avoided. 



ERYTHEMA CHRONICUM. 



Under this head are included the chapped hands of 

 human beings, the cracked heels of horses, and the chaps 

 which occur on the teats of newly calved cows, or on the 

 udders of ewes and lips of iambs. I have seen remarkable 

 attacks of this disease in well-kept flocks at spring-time, 

 when the animals were plethoric. 



In the horse, cracked heels may be divided under two 

 heads: firstly, those that are recent, and amount to super- 

 ficial excoriations ; and those that are deep, and consist in in- 

 dolent and sometimes sloughing ulcers. The recent or acute 

 cracked heels become chronic and confirmed by inattention, 

 but often the unfavourable character of the ulceration appears 

 from the commencement, owing to a special constitutional 

 state.
